Abstract

L'invention concerne une protéine prion humaine, PrP, qui présente sélectivement l'épitope MDEYSNQNN (SEQ ID No. 14) lorsque PrP est mal repliée. La forme mal repliée de la PrP humaine est associée à divers états de maladie. La présente invention concerne un anticorps utile pour détecter et traiter de telles maladies, notamment le cancer, tel que le cancer de l'ovaire et des lymphomes, et des encéphalopathies spongiformes transmissibles, telles que CJD. L'invention concerne également un immuno-conjugué dans lequel l'anticorps est conjugué à l'uréase en tant que cytotoxine.
